Holy fricking smokers... It's been three years and this thread has not amassed another single reply. The absolute patheticality of the PDN community... I understand every point this post makes and I too have the same struggles as described in this post. Some people just don't understand humans aren't robots and people can make mistakes.
But here I am, my PDN process not responding for seven hours. TL;DR, I accidentally hit CTRL+S when I was editing a PDN file that I meant to do only temporarily (ie. make some changes, flatten, copy image, paste image, then exit without saving), but I continued on thinking that I would be able to undo all my changes and go back to when I opened the image and CTRL+S it back, but when I finally did, PDN decided to freeze and I waited for 7 hours with still no change... I even tried increasing my memory priority with task manager...no change. I tried closing all my other processes...No change. PDN isn't even using any CPU in the task manager. I don't even know why or how it's managed to be frozen this long.
Now I'm just trying to find out how to potentially save the temporary cache my current PDN process so I can recover my history and potentially restore the process to its previous state when I reopen it. But, as it turns out, NOBODY has even thought about this which makes my hair fall. The sheer unthoughtfulness and inactivity of the PDN community boggles my mind. I have no words but to say that this PDN project that I've been saving on my computer for an entire year is now gone and replaced with some temporary changes I made. Go ahead, tell me all you want to "MAKE BACKUPS AND BE MORE ORGANISED NEXT TIME". It's too freaking late. Why can't you just give me an actual solution?
